Areas affected...southeast Lower Michigan

Concerning...Severe Thunderstorm Watch 26...

Valid 280713Z - 280915Z

The severe weather threat for Severe Thunderstorm Watch 26
continues.

SUMMARY...A severe threat is expected to continue across parts of
southeast Lower Michigan over the next 1 to 2 hours. Additional
weather watch issuance will not be needed, but an extension in area
could be done if necessary.

DISCUSSION...The latest high-resolution radar from Detroit shows a
disjointed line of strong to severe storms ongoing 30 to 40 statute
miles to the north of Detroit. The line of storms is being supported
by a subtle shortwave trough, and an associated vorticity max,
located over Lower Michigan evident on water vapor imagery. RAP
analysis data suggests the MLCAPE is around 500 J/kg, and WSR-88D
VWPs have 45 to 50 knots of 0-6 km shear. This should support
isolated supercells capable of producing wind damage and isolated
large hail. 0-3 km storm-relative helicity around 225 m2/s2 may also
be sufficient for a brief tornado as well.
